Last updated on AUGUST 23, 2021

Applies to:

Oracle TimesTen In-Memory Database - Version 11.2.1.8.0 to 11.2.1.9.6 [Release 11.2]
Oracle TimesTen In-Memory Database - Version 11.2.2.4.0 and later
Information in this document applies to any platform.

Symptoms

After Return Service is disabled, the "marked enable" message in ttmesg.log is appearing after second insert even though time took for first insert is below resume return.

Here is the scenario, below steps followed

 
As per Documentation,

When this RESUME RETURN attribute is set and return service blocking has been disabled for a subscriber, the return receipt or return twosafe service is re-enabled when the commit-to-acknowledge time for a transaction falls below the value set by RESUME RETURN. The commit-to-acknowledge time is the latency between when the application issues a commit and when the primary receives acknowledgement of the update from the subscriber.

So in the Step (7) itself the return service should get enabled.
